Kef LS50


Are these speakers really that good ?       are there any weaknesses of these speakers that one should consider before buying them ?

looking for a monitor speaker that has a low sensitivity and these have me thinking about them.

had a pair of Dali Zensors that I really like , but the tweeter went out in one of the speakers and looking for a replacement.

other ideas welcome....and looking for a monitor in the $500-1200 range

equipment used is 

ayre cd player
innersound esl 300 amp
aric audio tube preamp.
2 svs subs
birdscantrow
I'm the old man out, I have a pair and I don't think they are that great, tweeter is a little dull. I put a super tweeter on them for a while and they sounded much better. 
Great little speaker, good dynamics.  I like the ELAC Unifi UB5 more.

Can we say they look good too: get a color thats nots gold and black.  I got the white with blue drivers.

I push them with the following gears to test:

Preamp: Schiit Freya+, NAD 1155, Emotiva PT-100
Amps: Yam MX-1, NAD2200
Looking for a low sensitivity speaker?  Thats a first.  Kinda like looking for a girl to date that stinks.
